gtktreeview question

[Alexander Nagel <alexander acwn de>]

Hi,

I have a working gtktreeview in a scrolledwindow and i can scroll by 
mouse and even the iteration trough the list works, but i can't scroll 
automatically with this code snippet:

path = gtk_tree_model_get_path (GTK_TREE_MODEL (store), &itern);    

gtk_tree_view_scroll_to_cell (GTK_TREE_VIEW (tree), path,
        gtk_tree_view_get_column (GTK_TREE_VIEW (tree), 0), TRUE, 0.5, 0.0);

gtk_tree_view_set_cursor (GTK_TREE_VIEW (tree), path,
        gtk_tree_view_get_column (GTK_TREE_VIEW (tree), 0), FALSE);

gtk_tree_path_free (path);

What did I miss?
Any ideas?
Alexander
